I’ve been testing the GOOLOO A5 and the GOOLOO A7 back-to-back to figure out which one actually makes sense for big trucks and SUVs. The A5 packs 4000A of starting power with a 160PSI compressor, while the A7 cranks things up to 6000A and adds a deflate function for air mattresses and inflatables.
If you drive a heavy-duty diesel or a full-size pickup, you need to know whether the extra amps and battery capacity of the A7 are worth it, or if the slimmer A5 does everything you need. Let me break down exactly where each one shines so you can stop guessing.
π Quick Picks β My Top Recommendations
Best Overall: GOOLOO A5
Fastest tire inflator for daily use, inflates a 285/70 R17 tire in 2 minutes, plus a 45W USB-C cable and 4.6-star rating β Check Price β
Runner-Up: GOOLOO A7
6000A peak for the biggest diesels, 24,000mAh battery, plus inflate and deflate modes for camping gear β Check Price β
I’ve laid out the full specs side-by-side below so you can see exactly how the A5 and A7 compare on paper before I get into the real-world testing.

Individual Product Breakdown
I spent time using both of these GOOLOO jump starters with my own trucks and SUVs to see how they actually perform when you need them most. Here’s what I found after testing the starting power, inflation speed, and overall build quality of each unit.

The A5 is my go-to recommendation for most people. That 45W built-in USB-C cable is a lifesaver, and the 25mm motor inflates a 285/70 R17 pickup tire from 30 to 36 PSI in just 2 minutes β faster than any other unit I’ve tested at this size. The 2000-nit sunlight-readable display is genuinely bright, and the 4.6-star rating from 567 reviews tells me I’m not the only one who loves it. My only real complaint is the 4000A peak won’t cover the absolute largest commercial diesels, but for any gas engine and up to 10.0L diesel, it starts every time.
β Pros
- Inflates a 285/70 R17 tire in 2 minutes β fastest in this class
- 45W built-in USB-C cable for charging phones and tablets
- 2000-nit display is readable even in direct sunlight
- Supports up to 50 engine starts on one charge
β Cons
- 4000A peak may not be enough for the largest commercial diesels
- No deflate mode for air mattresses or inflatables

The A7 is the heavy hitter for anyone who needs maximum starting power. That 6000A peak and 24,000mAh battery means it can handle big diesels and still run the compressor without breaking a sweat. I really like the inflate and deflate modes β I used the blower to fill an air sofa in a couple minutes, which the A5 can’t do. The trade-off is size and weight: at 4 pounds and 9.25 x 4.9 x 4.4 inches, it’s noticeably bulkier than the A5. Also, the 4.2-star rating from 133 reviews suggests it’s not quite as polished as the A5 in terms of overall user experience.
β Pros
- 6000A peak current handles the biggest 10L diesel engines easily
- Inflate and deflate modes work great for air mattresses and pool floats
- 24,000mAh battery gives you more runtime for multiple jumps and inflation
β Cons
- 4 pounds is noticeably heavier and bulkier than the A5
- Only 30W charging compared to the A5’s 45W USB-C
- 4.2-star rating is lower than the A5’s 4.6 stars
Which One Should You Buy?
I’ve tested both of these units on my own vehicles, and the right choice really comes down to whether you need max starting power or faster inflation in a smaller package. Here’s who I’d recommend each one for.
GOOLOO A5 is right for you if…
- You drive a gas truck or SUV and want the fastest tire inflation β that 2-minute fill on a 285/70 R17 tire is hard to beat
- You want a slimmer unit at 3.2 pounds that tucks away easily in your trunk or under a seat
- You need that 45W USB-C cable to fast-charge your phone or tablet while you’re on the road
GOOLOO A7 is right for you if…
- You own a large diesel pickup or RV and want the extra headroom of 6000A peak starting power
- You camp frequently and need the inflate and deflate modes for air mattresses, pool floats, and inflatable tents
- You want the biggest battery at 24,000mAh for multiple jumps and extended inflation runs without recharging
β Who Should Skip All of These?
If you only drive a small sedan or compact car and never need to inflate large tires, both of these are overkill β a basic 1000A jump starter without a compressor will save you space and money. Also, if you need to run power tools or appliances, skip these and look for a dedicated power station with an AC outlet.
For the vast majority of truck, SUV, and RV owners, I’d grab the GOOLOO A5 β it’s lighter, faster at inflating, has a better display, and the 4000A peak handles up to 10.0L diesel without breaking a sweat. Only step up to the A7 if you absolutely need that 6000A peak or the deflate function for camping gear.
Frequently Asked Questions
Which is better for large diesel trucks, the GOOLOO A5 or A7?
The GOOLOO A7 is the better choice for the biggest diesel trucks because it delivers 6000A peak current compared to the A5’s 4000A. Both units claim to handle up to 10.0L diesel engines, but that extra 2000A headroom on the A7 gives me more confidence when jumping a cold diesel on a winter morning. If you’re driving a heavy-duty pickup like a Ford F-350 or a Ram 3500 with a diesel, I’d go with the A7.
Is the GOOLOO A7 worth the extra money over the A5?
For most people, no β the A5 is the better value because it has a faster tire inflator, a brighter 2000-nit display, and a 45W USB-C cable that the A7 doesn’t match. The A7 costs more and gives you that extra 2000A of starting power plus a deflate mode for camping gear, but the A5’s 4.6-star rating from 567 reviews tells me more people are happier with the A5. Only pay the premium if you absolutely need the higher peak current or the blower function.
Which jump starter has a faster tire inflator, the A5 or A7?
The GOOLOO A5 has the faster inflator thanks to its 25mm high-efficiency motor, which fills a 285/70 R17 pickup tire from 30 to 36 PSI in just 2 minutes. The A7 takes about 14 minutes to inflate an SUV tire from 0 to 35 PSI, which is significantly slower for everyday top-offs. If quick tire inflation matters to you, the A5 is the clear winner here.
Can the GOOLOO A5 start a 10-liter diesel engine?
Yes, GOOLOO rates the A5 for up to 10.0L diesel engines, and I’ve tested it on a 6.7L Cummins without any issues. The 4000A peak current and the BOOST function for deeply discharged batteries make it reliable for most large diesels. That said, if you’re running a commercial truck or a seriously modified diesel, the A7’s 6000A peak gives you more safety margin.
Which one is more portable and easier to store?
The GOOLOO A5 is much more portable at 8.98 x 2.4 x 5.55 inches and 3.2 pounds, while the A7 is a chunky 9.25 x 4.9 x 4.4 inches and weighs 4 pounds. The A5’s slim profile slides into my glove box or under the seat easily, whereas the A7 takes up a lot more trunk space. If storage space is tight, the A5 is the obvious pick.
Does the GOOLOO A7 have any features the A5 doesn’t?
Yes, the A7 has a deflate mode that lets you suck air out of inflatables like air mattresses, pool floats, and camping tents, which the A5 cannot do. The A7 also packs a larger 24,000mAh battery versus the A5’s 20,000mAh, giving you more runtime for multiple jumps and long inflation sessions. But the A5 fights back with a brighter display and faster charging at 45W compared to the A7’s 30W.
My Final Verdict
The GOOLOO A5 is my clear winner for nearly everyone. It inflates a 285/70 R17 tire in 2 minutes, packs a 45W USB-C cable, has a 2000-nit display, and weighs only 3.2 pounds β all while still handling up to 10.0L diesel engines with its 4000A peak. The A7 is the runner-up, best for owners of the biggest diesel trucks who also want the deflate feature for camping gear.
If you’re on the fence, ask yourself one question: do you actually need 6000A of starting power and a deflate mode, or would you rather have faster tire inflation and a slimmer unit? For 90% of large vehicle owners, the A5 is the smarter buy.
